The AppendText method creates a StreamWriter object that appends UTF-8 encoded text to an existing text file.

string fileName = @"C:fileName.txt";
FileInfo filetoappend = new FileInfo(fileName);
using (StreamWriter sw = filetoappend.AppendText())
{
   sw.WriteLine("--------- Append Text Start ----------");
   sw.WriteLine("New author started");
   sw.WriteLine("a book on Files Programming ");
   sw.WriteLine("using C#");
   sw.WriteLine("--------- Append Text End ----------");
}
// Read all text
string readText = File.ReadAllText(fileName);
Console.WriteLine(readText);
